Abstract: PURPOSE:To enable the change-over of mode order without decreasing oscillation efficiency, by providing an auxiliary total reflection mirror to reflect the reflected light from a total reflection mirror, and making the angle of the total reflection mirror changeable. CONSTITUTION:The angle positions of a total reflection mirror 2 and an auxiliary total reflection mirror 5 are set as shown by solid lines.

Thereby the laser light can be reflected in the z-shaped optical path of a1-a3. That is, when the distance between a partial reflection mirror 1 and the total reflection mirror 2 is l, the length of a laser light resonator becomes nearly 3l. When the angle position of the auxiliary reflection mirror 5 is set as shown by a dotted line, the resonator length becomes 2l. In this case, the laser light reflected by the total reflection mirror 2 is reflected by the auxiliary total reflection mirror 5, and enters again the total reflection mirror 2. When the angle position of the total reflection mirror 2 is set as shown by a dotted line in the manner in which the laser light entering the total reflection mirror 2 is made again to enter the partial reflection mirror 1, the resonator length becomes l. As the mode order is switched by changing the resonator length, the decrease of oscillation efficiency and laser output can be prevented.

Abstract: PURPOSE:To lessen a pressure difference between the pressure at the upstream and that in the downstream and miniaturize the captioned valve, by forming a closing valve by means of both a valve seat, or a tip of a sleeve-shaped moving iron core, and a mating, soft sealing member. CONSTITUTION:One end of a sleeve-shaped moving iron core 4 faces, as a valve seat end 4a, an abutting sealing member 3 made of soft material, while the other end is pushed by a pushing spring 5 for closing, thereby forming a magnetic circuit. Thus, the area, which is subject to a pressure difference between the pressure at the upstream and that in the downstream, is reduced because it is limited by the sleeve-shaped valve seat end 4a.
